Œ
SIZE - Amount of memory allocated for this area that contains the data, Index, or Log Area blocks. This is the amount used, not the size specified in the Multi-User startup options. SIZE values are printed as follows:
  • Numbers 1 through 9999 are printed with a blank terminator, for example, 9999 is printed as 9999 followed by a blank.
  • Numbers 10000 through 9999K are printed as n through nnnnK, rounded up.
  • Numbers 9999K plus one through 9999M are printed as n through nnnnM, rounded up.
  • Numbers above 9999M are printed with a G as the terminating character, rounded up.
BLOCKS - The number of data, Index, or Log Area blocks allocated to memory. COVERED is allocated in blocks and VIRTUAL is allocated in tracks.
Ž
SPACE - ADDRESS indicates use of normal partition memory.
MRDF READS - Provides the number of blocks that were read from the MRDF space instead of from disk.
VIRTUAL MRDF WRITES - Provides the number of blocks that were written to the MRDF VIRTUAL space.
COVERED 1ST/ACT READS - Provides the number of blocks read from disk for either a FIRST or ACTIVE COVERED area.
COVERED NON-1ST READS - For a COVERED FIRST area only, provides the number of blocks read from disk which do not reside in the MRDF buffers.
PERCENT - Indicates the amount of use based on the following:
REUSED
(COVERED ACTIVE areas only.)
Provides the percent of MRDF reads out of the total reads.
USED
(Virtual Areas Only.)
Provides the percent of the space allocated which was actually used to service program requests.
WITHIN
(COVERED FIRST areas only.)
Provides the percent of the total reads which occurred within the COVERED FIRST buffers.
